Product summary

SEAL-LOCK® Semi Flush is an integral casing connection that utilized the latest in Finite Element Analysis and physical testing technology during its development.

The design has multiple metal-to-metal seals; a close tolerance hooked thread form and an integrated torque shoulder that produces extremely high load capacities.

Specially designed relief grooves ensure hydraulic dope pressure will not interfere with designed pin/box bearing interface. The connection is well suited for the enhanced compressive, torsional and bending requirements of slim-hole directional well designs.
